Irish Spring soap in a bag.
Coyote urine (Yes, it is sold in bulk)
Fencing
"Deer-proof" flowers (They just bit off the flowers and spit them out)
Scarecrow
BUT....The ONLY thing that worked 100% was human hair!
Every time I got a haircut I would replenish it.
Worked like a charm!
Yup, human hair works...but it’s quite a job keeping it fresh (only lasts a few weeks) on a 75’x 75’ garden.......
